Definition
Work order aging measures the elapsed time since each open work order was created or approved, typically grouped into age bands (0–7 days, 8–30 days, 30+ days, and so on) to identify jobs that have stalled rather than progressed through normal execution. It complements backlog weeks by showing distribution and age, not just total volume.
Key facts
- Measures elapsed time per individual work order, typically grouped into age bands to spot stalled jobs.
- Complements backlog weeks: where backlog weeks shows total capacity demand, aging shows how long specific jobs have sat unaddressed.
- A large share of very old open work orders often signals prioritization, resourcing, or process problems rather than just volume.
- Distinct from the maintenance backlog itself, which is the set of open jobs, aging is a lens applied to that set.
How is Work order aging calculated?
Work order aging shows how long each individual open job has remained unaddressed since creation or approval, typically bucketed into age ranges so a team can see not just how much work is open, but which jobs are stalling and for how long.
What influences Work order aging?
The maintenance backlog is the full set of open, approved jobs. Backlog weeks converts that set into a total capacity-demand figure. Work order aging instead looks at the age distribution within that set, highlighting individual jobs that have been open unusually long, which raw backlog size or backlog weeks alone would not reveal.
